New Treatment Option for Chronic Obstructive Pulmonary Disease: Two Long-Acting Bronchodilators in a Single Metered-Dose Inhaler

Combination long-acting inhaled bronchodilators are central to the management of patients with moderate to very severe chronic obstructive pulmonary disease. Glycopyrrolate is a long-acting muscarinic antagonist (LAMA), and formoterol fumarate is a long-acting beta2 agonist (LABA). In randomized controlled trials, this LAMA/LABA combination in a metered-dose inhaler was shown to be effective in improving pulmonary function and quality of life. Clinicians now have the availability of 3 delivery systems for LAMA/LABA therapy, including metered-dose inhaler, dry-powder inhaler, and Soft Mist inhaler. On the basis of numerous patient factors, such as cognitive ability, manual strength/dexterity, and peak inspiratory flow, clinicians may select the most appropriate inhalation device. For each inhalation device, persistent patient education is absolutely essential, including observation of patient use. International evidence-based guidelines stress the critical importance of ensuring correct use of inhalation devices.
